- Abstract:
- The Metrological laboratory for angle and length calibration (ML160) uses a geodetic class doublefrequency GPS receiver as a time standard. Time correction terms are delivered to laboratory computers via Network Time Protocol (NTP). We tested NTP parameters within the intranet environment with the respect to the quality of GPS measurements. The 24 hours experiment showed that the characteristics of time delivered to NTP clients is influenced by the quality of GPS data received by our Stratum 1. We suggested methods for improving the reliability of GPS disciplined time corrections.
